 <p>You can run Demo Provider and Demo Consumer only, the default discovery strategy is Multicast by configuration center broadcast, do not run the two parts on the same machine, if you have to do so, set <code>unicast=false</code>, like <code>multicast://224.5.6.7:1234?unicast=false</code>, or the unicast send to consumer will be taken by provider, and the same for consumers. Only multicast has this issue</p>
 <p>You can run multiple Demo Provider and Demo consumer to verify load balance. Demo Consumer can run multi instance directly. Because of port conflict, you can either run multi Demo Providers on different machines or modify the value of <code>dubbo.protocol.port</code> in <code>conf/dubbo.properties</code> under the install directory of <code>conf/dubbo.properties</code></p>
 <p>You can add Simple Monitor as a monitor center, the default discovery strategy is Multicast by configuration center broadcast, display the dependency relationship, call times and cost</p>

 <p>After using Dubbo to serve or integrate applications, assuming that a service backstage log shows an exception and that the service is invoked by multiple applications, it is often difficult to determine which application is called, and what is the cause of the problem, so we need a set of distributed tracking systems to quickly locate the problem. Pinpoint can help us quickly locate problems (of course, there are more than one solution).</p>
 <h2>What is Pinpoint</h2>
 <p><a href="https://github.com/naver/pinpoint">Pinpoint</a> is an APM (Application Performance Management) tool for large-scale distributed systems written in Java. Inspired by Dapper, Pinpoint provides a solution to help analyze the overall structure of the system and how components within them are interconnected by tracing transactions across distributed applications.</p>

 <p>Dubbo's protocol, communication, serialization, registry, load balancing and other SPI all offer alternative strategies for different application scenarios while our test cases are very scattered. Ours is always uncertain whether it can satisfy the complete contract of the extension point when users need to add a new implementation.</p>
 <p>Thus we need to use TCK (Technology Compatibility Kit) for the core extension points.  When users add a new implementaion, compatibility with the rest of the framework can be ensured with TCK. This can effectively improve the overall health and also facilitate the access of the third party extenders, which accelerates the maturity of the open source community.</p>
 <p>Xingzhi from the open source community is already working on this part. His preliminary idea is to build a TCK framework for Dubbo drawing on the CDI-TCK of JBoss first, then realize the TCK implementing case of Dubbo.</p>

 <p>Dubbo Use microkernel + plugin design pattern. Microkernel is only responsible for assembling plugins, the functions of Dubbo are implemented by extension points(plugins), which means that all functions of Dubbo can be replaced by user customized extension.</p>
 <h2>Dubbo Ecosystem</h2>
 <p>We recommend you to put extension to Dubbo <a href="https://github.com/dubbo">ecosystem</a>. Using this pattern will keep the core repository cleaner and decrease the maintains work. With less code also speed up core repository build process.</p>

 <h2>Modularization</h2>
 <p>It is recommended to put service interfaces, service models, service exceptions, and so on in the API package,Because the service model and exception are part of the API, it is also in conformity with the modularization principle:Reusing the publish equivalence principle (REP) and the Common Reuse Principle (CRP).</p>
 <p>If you need, you can also consider placing a spring reference configuration in the API package, so that the user can only use the configuration in the spring loading process, and the configuration suggestion is placed in the package directory of the module, so as not to conflict, eg:<code>com/alibaba/china/xxx/dubbo-reference.xml</code>。</p>

 <p>If your application is simple enough, say, you do not need multi-registries or multi-protocols, and you want to share configuration among Spring containers. You can use <code>dubbo.properties</code> as default configuration.</p>
 <p>Dubbo will load dubbo.properties under the root of classpath automatically, you can also specify the path for loading this file by using JVM parameter: <code>-Ddubbo.properties.file=xxx.properties</code>.</p>

 <h2>Every service export to one specific protocol separately</h2>
 <p>Different protocol performance is not the same. Such as big data should use short connection protocol, small data and concurrent should use long connection protocol.</p>

 <p>Dubbo supports the same service to register multiple registries, or different services were registered to different registries, or even reference the same name service from different registries. In addition, the registry supports custom extensions <sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>。</p>
 <h2>One service register to multiple registries</h2>
 <p>For example: Alibaba some services are not deployed in Qingdao, only deployed in Hangzhou. While other applications in Qingdao need to reference this service, you can register your services to both registries at the same time.</p>

 <p>By default dubbo will check if the dependent service is available at startup . It will throw an exception to prevent Spring complete initialization when it is not available, so that you can find the problems early before publishing you application, the default setting: <code>check=true</code>.</p>
 <p>You can turn off checking by <code>check=false</code>. For example, some services do not care it when you run testing, or you must have one started firstly because of circular dependency.</p>
 <p>In addition, if your Spring bean is lazy-loaded or you delay reference service with API programming, turn off the check,

 <p>The instance of <code>ReferenceConfig</code> is heavy. It encapsulates the connection to the registry and the connection to the provider, so it need to be cached. Otherwise, repeatedly generating <code>ReferenceConfig</code> may cause performance problems , memory and connection leaks. This problem is easy to ignored when programming in API mode.</p>
 <p>Therefore, since <code>2.4.0</code>, dubbo provides a simple utility ReferenceConfigCache for caching instances of <code>ReferenceConfig</code>.</p>

 <p>The service container is a standalone launcher because the backend service does not require the functionality of a Web container ,such as Tomcat or JBoss. If you insist on using web containers to load service providers, that increase complexity and is waste of resources.</p>

 <p>The content of Service container can be extended, built-in spring, jetty, log4j etc..  This can be expanded with <a href="http://dubbo.apache.org/en-us/docs/dev/impls/container.html">Container Extension Points</a>. Configure it with the -D parameter in the java command or <code>dubbo.properties</code>.</p>

 <p>To facilitate the development of tests, it is common to have a registry of all services available in develop environment.And the registration of a service provider under development may affect consumers' inability to run.</p>
 <p>You can let service provider developers only subscribe to services only (services developed may rely on other services) ,don't register services under development and testing services under development with directly connection.</p>

 <p>Before the advent of large-scare services, an application might just exposes or references remote service by using RMI or Hessian, the call is done by configuring serive URL, and load balance is done through hardwares, like F5.</p>
 <p><strong>When there are more and more services, it becomes very difficult to configure the service URL, the single point pressure of F5 hardware load balancer is also increasing.</strong> At this point, a service registry is needed to dynamically register and discover services to make the service's location transparent. By obtaining the list of service provider addresses in the consumer side, the soft load balancing and Failover can be realized, this reduces the dependence on the F5 ha [...]

 <p>通过提供一个本地伪装的类，可以最大限度的控制出错之后的容错逻辑。有的时候，业务上并不需要这样灵活的机制，只有返回一个默认值的诉求，这个时候提供一个完整的本地伪装的实现就显得有点重了。或者线上出错的时候，应用并没有打包本地伪装，需要通过推送规则的方式临时对服务降级。Dubbo 框架为上面的这两种诉求都提供了快捷方式，帮助用户快速配置服务降级。</p>
 <p>启动服务端 <em>MockProvider</em> 之后，然后再执行 <em>MockConsumer</em> 就可以看到下面的结果：</p>

 <p>你也可以增加运行 Simple Monitor 监控中心，它缺省配置为通过 Multicast 注册中心广播发现 Provider 和 Consumer，并展示出它们的依赖关系，以及它们之间调用的次数和时间。</p>

 <p>在使用Dubbo进行服务化或者整合应用后，假设某个服务后台日志显示有异常，这个服务又被多个应用调用的情况下，我们通常很难判断是哪个应用调用的，问题的起因是什么，因此我们需要一套分布式跟踪系统来快速定位问题，Pinpoint可以帮助我们快速定位问题（当然，解决方案也不止这一种）。</p>

 <h2>Apache Skywalking(Incubator)简介</h2>
 <p><a href="https://github.com/apache/incubator-skywalking">Apache Skywalking(Incubator)</a> 专门为微服务架构和云原生架构系统而设计并且支持分布式链路追踪的APM系统。<a href="https://github.com/apache/incubator-skywalking">Apache Skywalking(Incubator)</a>通过加载探针的方式收集应用调用链路信息，并对采集的调用链路信息进行分析，生成应用间关系和服务间关系以及服务指标。<a href="https://github.com/apache/incubator-skywalking">Apache Skywalking (Incubating)</a>目前支持多种语言，其中包括<a href="https://github.com/apache/incubator-skywalking">Java</a>，<a href="https://github.com/OpenSkywalking/skyw [...]
 <p>目前Skywalking已经支持从6个可视化维度剖析分布式系统的运行情况。总览视图是应用和组件的全局视图，其中包括组件和应用数量，应用的告警波动，慢服务列表以及应用吞吐量；拓扑图从应用依赖关系出发，展现整个应用的拓扑关系；应用视图则是从单个应用的角度，展现应用的上下游关系，TopN的服务和服务器，JVM的相关信息以及对应的主机信息。服务视图关注单个服务入口的运行情况以及此服务的上下游依赖关系，依赖度，帮助用户针对单个服务的优化和监控；调用链展现了调用的单次请求经过的所有埋点以及每个埋点的执行时长；告警视图根据配置阈值针对应用、服务器、服务进行实时告警。</p>

 <p>Dubbo 的协议，通讯，序列化，注册中心，负载均策等扩展点，都有多种可选策略，以应对不同应用场景，而我们的测试用例很分散，当用户自己需要加一种新的实现时，总是不确定能否满足扩展点的完整契约。</p>
 <p>所以，我们需要对核心扩展点写 <a href="http://en.wikipedia.org/wiki/Technology_Compatibility_Kit">TCK</a> (Technology Compatibility Kit)，用户增加一种扩展实现，只需通过 TCK，即可确保与框架的其它部分兼容运行，可以有效提高整体健状性，也方便第三方扩展者接入，加速开源社区的成熟。</p>
 <p>开源社区的行知同学已着手研究这一块，他的初步想法是借鉴 JBoss 的 CDI-TCK，做一个 Dubbo 的 TCK 基础框架，在此之上实现 Dubbo 的扩展点 TCK 用例。</p>

 <p>Apache有一个官方的网站，用来维护所有的孵化项目的信息。每一个孵化项目在这个网站下都有一个信息页。
 Dubbo的信息页地址是https://incubator.apache.org/projects/dubbo.html。</p>
 <p>当项目发生比较大的变化，比如新的committer的加入，新的PMC的当选，或是新版本的Release等，都需要将这些更新信息维护到这个页面。

 <p>Dubbo使用微内核+插件的设计模式。内核只负责组装插件，Dubbo的功能都是由扩展点（插件）实现，这就意味着Dubbo的所有功能都可以被用户定制的扩展所替代。</p>
 <h3>Dubbo生态系统</h3>
 <p>我们建议您将扩展加入到Dubbo生态系统。使用这种模式，可以使Dubbo的核心仓库更干净，并且可以减少维护工作。更少的代码也可以提高核心仓库的构建速度。</p>

 <p>在 Dubbo 中，很多拓展都是通过 SPI 机制进行加载的，比如 Protocol、Cluster、LoadBalance 等。有时，有些拓展并不想在框架启动阶段被加载，而是希望在拓展方法被调用时，根据运行时参数进行加载。这听起来有些矛盾。拓展未被加载，那么拓展方法就无法被调用（静态方法除外）。拓展方法未被调用，拓展就无法被加载。对于这个矛盾的问题，Dubbo 通过自适应拓展机制很好的解决了。自适应拓展机制的实现逻辑比较复杂，首先 Dubbo 会为拓展接口生成具有代理功能的代码。然后通过 javassist 或 jdk 编译这段代码，得到 Class 类。最后再通过反射创建代理类，整个过程比较复杂。为了让大家对自适应拓展有一个感性的认识，下面我们通过一个示例进行演示。这是一个与汽车相关的例子，我们有一个车轮制造厂接口 WheelMaker：</p>

 <p>为了避免单点故障，现在的应用通常至少会部署在两台服务器上。对于一些负载比较高的服务，会部署更多的服务器。这样，在同一环境下的服务提供者数量会大于1。对于服务消费者来说，同一环境下出现了多个服务提供者。这时会出现一个问题，服务消费者需要决定选择哪个服务提供者进行调用。另外服务调用失败时的处理措施也是需要考虑的，是重试呢，还是抛出异常，亦或是只打印异常等。为了处理这些问题，Dubbo 定义了集群接口 Cluster 以及 Cluster Invoker。集群 Cluster 用途是将多个服务提供者合并为一个 Cluster Invoker，并将这个 Invoker 暴露给服务消费者。这样一来，服务消费者只需通过这个 Invoker 进行远程调用即可，至于具体调用哪个服务提供者，以及调用失败后如何处理等问题，现在都交给集群模块去处理。集群模块是服务提供者和服�
 ��消费者的中间层，为服务消费者屏蔽了服务提供者的情况，这样服务消费者就可以专心处理远程调用相关事宜。比如发请求，接受服务提供者返回的数据等。这就是集群的作用。</p>
 <p>Dubbo 提供了多种集群实现，包含但不限于 Failover Cluster、Failfast Cluster 和 Failsafe Cluster 等。每种集群实现类的用途不同，接下来会一一进行分析。</p>

 <p>本篇文章，将开始分析 Dubbo 集群容错方面的源码。集群容错源码包含四个部分，分别是服务目录 Directory、服务路由 Router、集群 Cluster 和负载均衡 LoadBalance。这几个部分的源码逻辑相对比较独立，我们将会分四篇文章进行分析。本篇文章作为集群容错的开篇文章，将和大家一起分析服务目录相关的源码。在进行深入分析之前，我们先来了解一下服务目录是什么。服务目录中存储了一些和服务提供者有关的信息，通过服务目录，服务消费者可获取到服务提供者的信息，比如 ip、端口、服务协议等。通过这些信息，服务消费者就可通过 Netty 等客户端进行远程调用。在一个服务集群中，服务提供者数量并不是一成不变的，如果集群中新增了一台机器，相应地在服务目录中就要新增一条服务提供者记录。或者，如果服务提供者的配置修改了，服务目录
 中的记录也要做相应的更新。如果这样说，服务目录和注册中心的功能不就雷同了吗？确实如此，这里这么说是为了方便大家理解。实际上服务目录在获取注册中心的服务配置信息后，会为每条配置信息生成一个 Invoker 对象，并把这个 Invoker 对象存 [...]
 <p>关于服务目录这里就先介绍这些，大家先有个大致印象。接下来我们通过继承体系图来了解一下服务目录的家族成员都有哪些。</p>

 <p>SPI 全称为 Service Provider Interface，是一种服务发现机制。SPI 的本质是将接口实现类的全限定名配置在文件中，并由服务加载器读取配置文件，加载实现类。这样可以在运行时，动态为接口替换实现类。正因此特性，我们可以很容易的通过 SPI 机制为我们的程序提供拓展功能。SPI 机制在第三方框架中也有所应用，比如 Dubbo 就是通过 SPI 机制加载所有的组件。不过，Dubbo 并未使用 Java 原生的 SPI 机制，而是对其进行了增强，使其能够更好的满足需求。在 Dubbo 中，SPI 是一个非常重要的模块。基于 SPI，我们可以很容易的对 Dubbo 进行拓展。如果大家想要学习 Dubbo 的源码，SPI 机制务必弄懂。接下来，我们先来了解一下 Java SPI 与 Dubbo SPI 的用法，然后再来分析 Dubbo SPI 的源码。</p>
 <p>需要特别说明的是，本篇文章以及本系列其他文章所分析的源码版本均为 <strong>dubbo-2.6.4</strong>。因此大家在阅读文章的过程中，需注意将代码版本切换到 dubbo-2.6.4 tag 上。</p>

 <p>本篇文章，我们来研究一下 Dubbo 导出服务的过程。Dubbo 服务导出过程始于 Spring 容器发布刷新事件，Dubbo 在接收到事件后，会立即执行服务导出逻辑。整个逻辑大致可分为三个部分，第一部分是前置工作，主要用于检查参数，组装 URL。第二部分是导出服务，包含导出服务到本地 (JVM)，和导出服务到远程两个过程。第三部分是向注册中心注册服务，用于服务发现。本篇文章将会对这三个部分代码进行详细的分析。</p>
 <h2>2.源码分析</h2>
 <p>服务导出的入口方法是 ServiceBean 的 onApplicationEvent。onApplicationEvent 是一个事件响应方法，该方法会在收到 Spring 上下文刷新事件后执行服务导出操作。方法代码如下：</p>

 <p>LoadBalance 中文意思为负载均衡，它的职责是将网络请求，或者其他形式的负载“均摊”到不同的机器上。避免集群中部分服务器压力过大，而另一些服务器比较空闲的情况。通过负载均衡，可以让每台服务器获取到适合自己处理能力的负载。在为高负载服务器分流的同时，还可以避免资源浪费，一举两得。负载均衡可分为软件负载均衡和硬件负载均衡。在我们日常开发中，一般很难接触到硬件负载均衡。但软件负载均衡还是可以接触到的，比如 Nginx。在 Dubbo 中，也有负载均衡的概念和相应的实现。Dubbo 需要对服务消费者的调用请求进行分配，避免少数服务提供者负载过大。服务提供者负载过大，会导致部分请求超时。因此将负载均衡到每个服务提供者上，是非常必要的。Dubbo 提供了4种负载均衡实现，分别是基于权重随机算法的 RandomLoadBalance�
 �基于最少活跃调用数算法的 LeastActiveLoadBalance、基于 hash 一致性的 ConsistentHashLoadBalance，以及基于加权轮询算法的 RoundRobinLoadBalance。这几个负载均衡算法代码 [...]
 <p>本系列文章在编写之初是基于 Dubbo 2.6.4 的，近期，Dubbo 2.6.5 发布了，其中就有针对对负载均衡部分的优化。因此我们在分析完 2.6.4 版本后的源码后，会另外分析 2.6.5 更新的部分。其他的就不多说了，进入正题吧。</p>

 <p>上一篇文章详细分析了服务导出的过程，本篇文章我们趁热打铁，继续分析服务引用过程。在 Dubbo 中，我们可以通过两种方式引用远程服务。第一种是使用服务直连的方式引用服务，第二种方式是基于注册中心进行引用。服务直连的方式仅适合在调试或测试服务的场景下使用，不适合在线上环境使用。因此，本文我将重点分析通过注册中心引用服务的过程。从注册中心中获取服务配置只是服务引用过程中的一环，除此之外，服务消费者还需要经历 Invoker 创建、代理类创建等步骤。这些步骤，将在后续章节中一一进行分析。</p>
 <h2>2.服务引用原理</h2>
 <p>Dubbo 服务引用的时机有两个，第一个是在 Spring 容器调用 ReferenceBean 的 afterPropertiesSet 方法时引用服务，第二个是在 ReferenceBean 对应的服务被注入到其他类中时引用。这两个引用服务的时机区别在于，第一个是饿汉式的，第二个是懒汉式的。默认情况下，Dubbo 使用懒汉式引用服务。如果需要使用饿汉式，可通过配置 &lt;dubbo:reference&gt; 的 init 属性开启。下面我们按照 Dubbo 默认配置进行分析，整个分析过程从 ReferenceBean 的 getObject 方法开始。当我们的服务被注入到其他类中时，Spring 会第一时间调用 getObject 方法，并由该方法执行服务引用逻辑。按照惯例，在进行具体工作之前，需先进行配置检查与收集工作。接着根据收集到的信息决定服务用的方式，有三种，第一种是引用本地 (JVM) 服务，第二是通过直连方式引用远程服务，第三是通过注册中心引�
 ��远程服务。不管是哪种引用方式，最后都会得到一个 Invoker 实例。如果有多个注册中心，多个服务提供 [...]

 <p>上一篇文章分析了集群容错的第一部分 — 服务目录 Directory。服务目录在刷新 Invoker 列表的过程中，会通过 Router 进行服务路由，筛选出符合路由规则的服务提供者。在详细分析服务路由的源码之前，先来介绍一下服务路由是什么。服务路由包含一条路由规则，路由规则决定了服务消费者的调用目标，即规定了服务消费者可调用哪些服务提供者。Dubbo 目前提供了三种服务路由实现，分别为条件路由 ConditionRouter、脚本路由 ScriptRouter 和标签路由 TagRouter。其中条件路由是我们最常使用的，标签路由是一个新的实现，暂时还未发布，该实现预计会在 2.7.x 版本中发布。本篇文章将分析条件路由相关源码，脚本路由和标签路由这里就不分析了。</p>

 <p>在前面的文章中，我们分析了 Dubbo SPI、服务导出与引入、以及集群容错方面的代码。经过前文的铺垫，本篇文章我们终于可以分析服务调用过程了。Dubbo 服务调用过程比较复杂，包含众多步骤，比如发送请求、编解码、服务降级、过滤器链处理、序列化、线程派发以及响应请求等步骤。限于篇幅原因，本篇文章无法对所有的步骤一一进行分析。本篇文章将会重点分析请求的发送与接收、编解码、线程派发以及响应的发送与接收等过程，至于服务降级、过滤器链和序列化大家自行进行分析，也可以将其当成一个黑盒，暂时忽略也没关系。介绍完本篇文章要分析的内容，接下来我们进入正题吧。</p>
 <h2>2. 源码分析</h2>
 <p>在进行源码分析之前，我们先来通过一张图了解 Dubbo 服务调用过程。</p>

 <h2>分包</h2>
 <p>建议将服务接口、服务模型、服务异常等均放在 API 包中，因为服务模型和异常也是 API 的一部分，这样做也符合分包原则：重用发布等价原则(REP)，共同重用原则(CRP)。</p>
 <p>如果需要，也可以考虑在 API 包中放置一份 Spring 的引用配置，这样使用方只需在 Spring 加载过程中引用此配置即可。配置建议放在模块的包目录下，以免冲突，如：<code>com/alibaba/china/xxx/dubbo-reference.xml</code>。</p>

 <p>此篇文档主要讲在<strong>应用启动阶段，Dubbo框架如何将所需要的配置采集起来</strong>（包括应用配置、注册中心配置、服务配置等），以完成服务的暴露和引用流程。</p>
 <p>根据驱动方式的不同（比如Spring或裸API编程）配置形式上肯定会有所差异，具体请参考<a href="./xml.md">XML配置</a>、<a href="./annotation.md">Annotation配置</a>、<a href="./api.md">API配置</a>三篇文档。除了外围驱动方式上的差异，Dubbo的配置读取总体上遵循了以下几个原则：</p>

 <p>Provider端异步执行将阻塞的业务从Dubbo内部线程池切换到业务自定义线程，避免Dubbo线程池的过度占用，有助于避免不同服务间的互相影响。异步执行无益于节省资源或提升RPC响应性能，因为如果业务执行需要阻塞，则始终还是要有线程来负责执行。</p>
 <blockquote>
 <p>注意：Provider端异步执行和Consumer端异步调用是相互独立的，你可以任意正交组合两端配置</p>

 <p>远程服务后，客户端通常只剩下接口，而实现全在服务器端，但提供方有些时候想在客户端也执行部分逻辑，比如：做 ThreadLocal 缓存，提前验证参数，调用失败后伪造容错数据等等，此时就需要在 API 中带上 Stub，客户端生成 Proxy 实例，会把 Proxy 通过构造函数传给 Stub <sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>，然后把 Stub 暴露给用户，Stub 可以决定要不要去调 Proxy。</p>

 <p>Dubbo 支持同一服务向多注册中心同时注册，或者不同服务分别注册到不同的注册中心上去，甚至可以同时引用注册在不同注册中心上的同名服务。另外，注册中心是支持自定义扩展的 <sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup>。</p>
 <h2>多注册中心注册</h2>
 <p>比如：中文站有些服务来不及在青岛部署，只在杭州部署，而青岛的其它应用需要引用此服务，就可以将服务同时注册到两个注册中心。</p>

 <p>Dubbo 缺省会在启动时检查依赖的服务是否可用，不可用时会抛出异常，阻止 Spring 初始化完成，以便上线时，能及早发现问题，默认  <code>check=&quot;true&quot;</code>。</p>
 <p>可以通过 <code>check=&quot;false&quot;</code> 关闭检查，比如，测试时，有些服务不关心，或者出现了循环依赖，必须有一方先启动。</p>
 <p>另外，如果你的 Spring 容器是懒加载的，或者通过 API 编程延迟引用服务，请关闭 check，否则服务临时不可用时，会抛出异常，拿到 null 引用，如果 <code>check=&quot;false&quot;</code>，总是会返回引用，当服务恢复时，能自动连上。</p>

 <p>服务容器只是一个简单的 Main 方法，并加载一个简单的 Spring 容器，用于暴露服务。</p>
 <p>服务容器的加载内容可以扩展，内置了 spring, jetty, log4j 等加载，可通过<a href="http://dubbo.apache.org/zh-cn/docs/dev/impls/container.html">容器扩展点</a>进行扩展。配置配在 java 命令的 -D 参数或者 <code>dubbo.properties</code> 中。</p>

 <p>dubbo provider中的服务配置项有接近<a href="http://dubbo.apache.org/en-us/docs/user/references/xml/dubbo-service.html">30个配置项</a>。 排除注册中心服务治理需要之外，很大一部分配置项是provider自己使用，不需要透传给消费者。这部分数据不需要进入注册中心，而只需要以key-value形式持久化存储。</p>
 <p>dubbo consumer中的配置项也有<a href="http://dubbo.apache.org/en-us/docs/user/references/xml/dubbo-reference.html">20+个配置项</a>。在注册中心之中，服务消费者列表中只需要关注application，version，group，ip，dubbo版本等少量配置，其他配置也可以以key-value形式持久化存储。</p>
 <p>这些数据是以服务为维度注册进入注册中心，导致了数据量的膨胀，进而引发注册中心(如zookeeper)的网络开销增大，性能降低。</p>

 <p>在大规模服务化之前，应用可能只是通过 RMI 或 Hessian 等工具，简单的暴露和引用远程服务，通过配置服务的URL地址进行调用，通过 F5 等硬件进行负载均衡。</p>
 <p><strong>当服务越来越多时，服务 URL 配置管理变得非常困难，F5 硬件负载均衡器的单点压力也越来越大。</strong> 此时需要一个服务注册中心，动态地注册和发现服务，使服务的位置透明。并通过在消费方获取服务提供方地址列表，实现软负载均衡和 Failover，降低对 F5 硬件负载均衡器的依赖，也能减少部分成本。</p>

 <p>dubbo provider中的服务配置项有接近<a href="http://dubbo.apache.org/en-us/docs/user/references/xml/dubbo-service.html">30个配置项</a>。 排除注册中心服务治理需要之外，很大一部分配置项是provider自己使用，不需要透传给消费者。这部分数据不需要进入注册中心，而只需要以key-value形式持久化存储。
 dubbo consumer中的配置项也有<a href="http://dubbo.apache.org/en-us/docs/user/references/xml/dubbo-reference.html">20+个配置项</a>。在注册中心之中，服务消费者列表中只需要关注application，version，group，ip，dubbo版本等少量配置，其他配置也可以以key-value形式持久化存储。
 这些数据是以服务为维度注册进入注册中心，导致了数据量的膨胀，进而引发注册中心(如zookeeper)的网络开销增大，性能降低。<br>

 <p>环境要求：需要<strong>Java 8</strong>及以上版本。</p>
 <p>2.7.0版本在改造的过程中遵循了一个原则，即<strong>保持与低版本的兼容性，因此从功能层面来说它是与2.6.x及更低版本完全兼容的</strong>，而接下来将要提到的兼容性问题主要是<a href="#%E5%8C%85%E5%90%8D%E6%94%B9%E9%80%A0">包重命名</a>带来的。另外，虽然功能用法保持向后兼容，但参考本文能帮助您尽快用到2.7.0版本的新特性。</p>
